Using 1.4beta6. When creating a [[Category:Whatever]] link when editing a page, and the category
has not yet been created, it will create the category when the link is clicked and the Category
page is edited. Then i included the same [[Category:Whatever]] link in another page - worked fine.
I returned to the original page where the first [[Category:Whatever]] link was made, and "Whatever"
was in red, which took me to ...whatever&action=edit, even though the edit box itself has the
category's info i entered the first time.
This only happens with the page that creates the category link when it doesn't exist yet. Only way
to fix it is to delete the page, logout as Sysop, login again and create it again with the exact
same source when deleted. Now the "Whatever" link is properly formatted (blue color), taking to the
category:whatever page.
Anyone notice this too? Any fixes i'm not aware of?

The wiki cache does not automatically have articles purged that reference a
newly created or deleted category, perhaps for performance reasons.
A better work-around is to use the action=purge option to flush the wiki cache,
e.g. .../index.php?title=The_article&action=purge
Caching at the wiki can be disabled by adding the following line to
LocalSettings.php
$wgEnableParserCache = false;
